Maximizing torque transmission in magnetorheological clutches#
Magnetorheological fluids (MRF) consist of magnetizable solid particles in carrier fluid. When applying an external magnetic field the particles become magnetized and form chains along the field lines. As a result, the MRF changes within milliseconds from a liquid to a solid state. This is very useful for targeted industrial applications, for example, clutches, shock absorbers and brakes. At the Fraunhofer IWM, MRF are modeled under real-life operating conditions at the particle level. In this way, a detailed and in-depth understanding of the MRF mechanisms at work is achieved, which allows the properties of the particles to be specifically optimized, in essence tailoring them to the desired application.
